Add an option to control hot-reload-on-save behaviour when using auto-save

[skateboarder]

Describe the bug
A clear and concise description of what the bug is.

To Reproduce
Steps to reproduce the behavior:

1. Run a project
2. Edit it while having the auto-save setting enabled

Expected behavior
On completion of auto-save, hot reload should've been triggered. But instead, its not triggered until manual save/reload

Versions (please complete the following information):

• VS Code version: 1.52.1
• Dart extension version: 3.19.1
• Dart/Flutter SDK version: 2.12.0-133.7.beta/1.25.0-8.3.pre

This is intended behavior! See #3033.

If this was working well for some, then I think it's probably fair to have a setting to control it (perhaps extend the existing setting to be an enum for on/off/manual or similar).

This is one of the best feature and why i chose VSCode as my primary IDE. Should've make it optional since it works well on mac. Just my 2 cents.

I guess I underestimated how many people were using this without issues! The dart.flutterHotReloadOnSave will be updated to be an enum in the next release:

dart.flutterHotReloadOnSave

Whether to automatically send a Hot Reload request during a debug session when saving files.

• never - do not reload when saving.
• always - reload for all saves, manual or automatic.
• manual - only reload for manual saves (requires pressing Save explicitly if using autosave).

This change hasn't landed yet, so keeping this open until it does.

Worked for me, Thanks..

Asking from @DanTup and @Malware656 to post a working screenshot.

Edit, Thanks to all, Everything is working fine 😄

In vs code, Go to extentions tab then fund dart, (which is installed) then click the settings icon. There you have to find how to see the settings.json file, then you have to pass this code,

"dart.debugExternalLibraries": false,
    "dart.debugSdkLibraries": false,
    "dart.allowTestsOutsideTestFolder": true,
    "dart.flutterHotReloadOnSave" : "always", // < ---- This is the added code.

Now if you run it will work like swift.
